|  | AO Industries uses and supports a variety of open source technologies
in the hosting and development environment we provide. Open source
software has many inherent benefits over normally licensed software.
Open source software is cheaper than conventional software to use
and to maintain. At the same time, it loses none of the reliability
or functionality that conventional software possesses, often surpassing
conventional software in both usability and effectiveness. For more
information about open source software, you may visit the Open Source Initiative Homepage.
A brief listing of some of the packages we employ appears below.  For a searchable database of every supported
software package, please see our Package List |  |
